Note:
Note:
• none
• none
• DMA Engine Device Driver is loaded and takes responsibility of all DMA Engine devices
• Reads CB_BAR to discover DMA Engine Integrated Device capabilities and per Port
• Does nothing - waits for I/O Software Driver to configure and enable the I/O device.
• Driver loads
• DMA Engine’s Root Complex Integrated Device requires Device Driver
• Client Device Driver must load after DMA Engine Device Driver.
• N/A - the chipset still supports CB_Query
• none
• Exposes DMA Engine via DMA Engine Driver Software I/F
• Store Client CFG info from I/O device driver
• Using Client’s CFG info, detect which Root Port serves Client Device.
• Waits for its software driver to program the I/O device and command it to use DMA
• Searches & detects DMA Engine Driver’s Software I/F
• Registers with DMA Engine driver’s software I/F
• Query for DMA Engine services via DMA Engine driver’s software I/F
• Passes Client’s Requestor ID and CFG Information via DMA Engine driver’s software I/
• Use Client PCI Express* Hierarchy location to determine if DMA Engine Port services
• None
• None
• Programs DMA Engine registers for Client Device reserving DMA Engine resource
• Waits for its software driver to command it to use DMA Engine resources
• Via DMA Engine software driver, client reserves and configures specific DMA Engine
• Restriction: Each DMA Engine resource can have exactly one owner, and sharing is not
